TERMINOLOGY

This development module uses option selection jumpers and cut-traces to setup default

configuration. Terminology for application of the option jumpers is as follows:

Jumper – a plastic shunt that connects 2 terminals electrically

Jumper on, in, or installed - jumper is installed such that 2 pins are connected together

Jumper off, out, or idle - jumper is installed on 1 pin only. It is recommended that

jumpers be idled by installing on 1 pin so they will not be lost.

Cut-Trace – a circuit trace connection between component pads. The circuit trace may

be cut using a razor knife to break the default connection. To reconnect the circuit,

simply install a suitably sized 0-ohm resistor or attach a wire across the pads.

GETTING STARTED

The CSM-56F801 single board computer is a fully assembled, fully functional development

module for the Freescale DSP56F801 digital signal processor. The module comes with a

serial cable, power supply, and installed binary monitor for stand-alone operation. Support

software for this development module is provided for Windows 95/98/NT/2000/XP operating

systems.

Users should be familiar with the hardware and software operation of the target MPU. Refer to

the DSP56F801 User Manual and Reference Manual for details on MPU operation. The

module’s purpose is to promote the features of the DSP56F801 and to assist the user in

quickly developing an application in a known working environment. Users should be familiar

with memory mapping, memory types, and embedded software design for quick, successful,

application development.

Use of the CSM-56F801 module requires Metrowerks CodeWarrior for Freescale DSP and an

Axiom Manufacturing JTAG cable. Both items are available in the CSM-56F801KIT. The

JTAG cable supports communications between the CSM-56F801 module and a standard PC.

CSM-56F801 OPERATION

The CSM-56F801 module provides input and output features to assist embedded application

development. Access to MPU port signals is available through connector J1. This connector

may also be used to input power to the module or to output power to attached modules. RS-

232 communications signals may also be input through connector J1. Care must be exercised

when using the J1 to power the module, as only regulated +3.3VDC (+/- 5%) should be

supplied to this connection

Five option jumpers and 3 cut-traces control module operation. Enabling a jumper option

requires installing a shunt across the associated header pins. Removing the shunt disables

the associated option. An option enabled by a cut-trace can be disabled by removing the

circuit trace between the cut-trace component pads. Use a sharp knife to cut the embedded

circuit trace. Be careful not to damage adjacent circuitry. To re-enable the option, simply

install a suitably sized 0-ohm resistor or piece of wire across the cut-trace component pads.

MEMORY MAP

The DSP56F801 utilizes two independent memory spaces, data and program, configured in a

Harvard architecture. RAM and Flash memory are used for on-chip data memory and on-chip

program memory. Refer to the DSP56F801 User Guide for details on accessing Program and

Data memory.

Power Supply

Power is supplied to the module through a 2mm barrel connector at location PWR or through

connector J1. Power may also be sourced off-module through connector J1. The PWR_SEL

jumper determines the source of input power.

PWR

The PWR barrel connector accepts 2.0 – 2.1 mm barrel plug and allows the module to be

powered from a transformer plugged into a standard wall outlet. Input voltage should be limited

to between +4VDC and +12VDC. Input voltage of +9VDC @ 200 mA is typical.

Connector J1

Power may be supplied to the module through the pins J1-1 and J1-2. Use of this option

requires a regulated voltage input limited to +3.3VDC (+/- 5%). This input is connected directly

to the module power and ground planes. Care should be exercised not to over-drive this input.

This connection may also be used to power external modules attached to connector J1. The

PWR_SEL option header determines how power is routed to the module.

Freescale Semiconductor, Inc.

DOC-0334-010, REV D DECEMBER 2, 2005

PWR_SEL

The PWR_SEL jumper selects the source of power input to the DSP-56F801 module or allows

regulated +3.3VDC to be provided to J1 for use by external circuits. The module may be

powered from the 2.0mm barrel connector (PWR) or from the 40-pin MCU connector (J1).

Power input at the PWR jack must be DC voltage between +5V and +16V. Power input on the

MCU connector must be regulated voltage between +3.0VDC and +3.3VDC. The

MCU_PORT connector input allows use of batteries, or other alternate sources, to power the

module. Damage may occur if the MCU_PORT power input pins are over-driven. Refer to the

table below to determine correct PWR_SEL jumper setting.

CAUTION: Module damage may occur if the MCU_PORT power input pin (J1-1) is over-driven.

The PWR_SEL option jumper provides 3 possible configurations; source power from the PWR

connector, source power from J1, or source power from PWR and supply power to J1. The

figures below show the settings for each configuration.

Reset Switch

The RESET switch provides a method to apply an asynchronous reset to the module.

Pressing the RESET switch applies a low voltage level to the RESET input. Logic on this

signal prevents unwanted RESET inputs to the MPU.

Low-Voltage Detect

The MPU includes an internal POR and Low-Voltage Interrupt circuit. This circuit protects

against low-voltage and under-voltage conditions. The system consists of a POR circuit and a

low-voltage interrupt (LVI) circuit. The POR circuit holds the MPU in reset until voltage

reaches an acceptable level. The LVI provides an interrupt out when voltage falls below the

trip level. Refer to the MPU User Guide for further details.

Freescale Semiconductor, Inc.

DOC-0334-010, REV D DECEMBER 2, 2005

Timing

The MPU function from either an internal relaxation oscillator or an external timing source. A

location for an external timing source has been provided. Component size for the external

timing source is based on an 8 MHz ceramic resonator from Panasonic, P/N EFO-S8004E5A.

This part is not populated in the default module configuration. Refer to the MPU User Guide for

further details

Communications

The CSM-56F801 module provides a single RS-232 communications port. An RS-232

transceiver (U2) provides RS-232 signal level to TTL/CMOS logic level translation on the first

RS-232 channel. RS232 signals TXD0 and RXD0 are routed between the transceiver and the

MCU. These signals are also routed to connector J1. RS-232 communication signals input on

J1 must be TTL/CMOS logic levels; no translation support is provided through this path. The

transceiver output may also be driven off-module if the signals are suitably buffered. As added

development support, hardware flow control signals RTS and CTS are available on the logic

side of U2. These signals are routed to vias located near the transceiver (U2). RTS has been

biased properly to support 2-wire RS-232 communications.

Use of the J1 connector to input RS-232 signals requires disabling the on-board RS-232

transceiver. Otherwise, signal corruption may occur. Disabling the on-board transceiver is

accomplished by opening cut-traces CT4, and CT5. Simply remove the circuit trace between

the cut-trace pads to open the circuit. To restore the circuit functionality, install a 1206 size, 0-

ohm, resistor or a short piece of wire across the cut-trace pads.

COM Connector

A standard 9-pin Dsub connector provides external connections for the COM port. The COM

port is used by default with the debug monitor. Component U2 provides RS-232 translation

services. The figure below details the DB9 connector.

User Options

Indicators LED1 and LED2 are connected to the MPU I/O ports by the USER option bank.

When the appropriate USER jumper is installed, the assigned LED is active. Each LED is

active low. A low voltage level driven out on the appropriate MPU port causes the LED to light.

MPU ports PWMA0 and PWMA1 drive LED1 and LED2 respectively.

Two push button switches provide momentary, active low, input to the MPU for user

applications. Switches SW1 and SW2 are connected to the MPU I/O ports by the USER

option bank. SW1 and SW2 provide input to MCUI/O ports TD0 and TD1 respectively. The

table below shows the user jumper settings.
